Hello Friends, In this post I make a 200 Watt mono amplifier using 2pcs. IRF540N and IRF9540N MOSFET. For driver of this amplifier I use LM393 IC. For make coil of this amplifier, must use LCR meter. Because 50% sound clarity is depended on it's coil, and 50% on circuit. For designing my PCB, I used EasyEda online software. Then I export the Gerber file (which you can download). And then I go to PCBWay for manufacturing my PCB. PCBWay are the largest PCB manufacturer in China. They offer Standard PCB, Advanced PCB, Rigid-Flex PCB, SMD-Stencil and PCB Assembly Service. Here you get, 100x100mm 2 Layer PCB only at $5, And processing time within 24 hours. And they distribute, worldwide. The more you order, the less price you have to pay.
You must upload the Gerber File and select the quantity, color, silkscreen, thickness, etc. Then choose your country, and shipping method, and then Pay. PCBWay will deliver your PCB within 7-10 days.
After one week I received my PCB. You can see the PCB quality, it's awesome. I ordered Red PCB. But you can choose your PCB color. PCBWay provides 9 color solder masks - Green, Blue, Red, Purple, Black, White, Yellow, Matte Black, and Matte Green. On PCBWay you can get 100x100mm 2 Layer PCB only at $5. Maximum size PCB you can get 500x1100mm. The maximum Layer is up to 14 Layers. If you order PCB for the first time at PCBWay, you get a $5 discount coupon. So upload your Gerber today and get the best quality PCB.

Testing Method After Complete This Amplifier
Series light test:- After complete this board don't forget to series light test. When you will on this amplifier via series light, it glow for some time (1 - 2 sec). Then series light will turned off fully. If the series light will fully turned off, then check the voltages.
Check Voltages:- Check Speaker Output and Audio Input voltage. Here you get no voltages 0.00V. If you get same voltages, then connect preamplifier to input and connect speaker to output.
Power Supply:- Recommended transformer 30-0-30V to 35-0-35V 5A.
